Find LCM of 774,909,992,665,841 with Prime Factorization
| 2 | 774, 909, 992, 665, 841 |
| 3 | 387, 909, 496, 665, 841 |
| 3 | 129, 303, 496, 665, 841 |
| 43, 101, 496, 665, 841 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 43 x 101 x 496 x 665 x 841 = 21685111126560
Therefore, the lowest common multiple of 774,909,992,665,841 is 21685111126560.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
774 x 909 x 992 x 665 x 841 = 390332000278080
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
909 : 1, 3, 9, 101, 303, 909
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
665 : 1, 5, 7, 19, 35, 95, 133, 665
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,909,992,665,841, is 1.
Now, the common factors can be found like this.
774:2x 3x 3x 43
909:3x 3x 101
992:2x 2x 2x 2x 2x 31
665:5x 7x 19
841:29x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 390332000278080/(1x18)
LCM = 390332000278080/18
LCM = 21685111126560
Thus, we can understand that the LCM of 774,909,992,665,841 is 21685111126560.
